This Friday (the 12th) I’m presenting a live webinar on How Routers Really Work over at Pearson. From the description:

This training will peer into the internal components of a router, starting with an explanation of how a router switches packets. This walk through of a switching path, in turn, will be used as a foundation for explaining the components of a router, including the various tables used to build forwarding tables and the software components used to build these tables.

I’ve changed just a few of the slides from the last time I gave this talk and reordered some things.

In the aftermath of a major network outage, the natural reaction of most network engineers is to find some way to avoid all future outages—regardless of the cost. The first line of defense against is future outages is redundancy, whether in the form of additional parallel links, new routers, new firewalls, new … whatever, so long as there is more of it so packets have more paths to make it from source to destination.

Please join me for this live webinar.

I’m teaching my troubleshooting webinar this Friday. I’ve revamped the slides entirely, so this will likely be a big change for anyone who’s attended previous versions of this. Three hours, 109 slides, and interaction through the chat window … all to develop some really good skills in how to troubleshoot. For those who are curious, I was taught formal troubleshooting skills in my early life in electronics, learning my lessons on ILS, RADAR, and radio systems of various kinds. This webinar is my adaptation of those skills for network engineers.

The Hedge is over 90 episodes now … I’m a little biased, but I believe we’re building the best content in network engineering—a good blend of soft skills, Internet policy, research, open source projects, and relevant technical content. You can always follow the Hedge here on Rule 11, of course, but it’s also available on a number of services, including—

• iTunes
• Spotify
• Deezer
• Castbox
• Google
• Luminary
• Pocket Casts

I think it’s also available on Amazon Music, but I don’t subscribe to that service so I can’t see it. You can check the Podcast Directory for other services, as well. If you enjoy the Hedge, please post a positive rating so others can find it more easily.

I’ll be teaching a three-hour live webinar on data center fabrics on the 20th of August—

Data centers are the foundation of the cloud, whether private, public, on the edge, or in the center of the network. This training will focus on topologies and control planes, including scale, performance, and centralization. This training is important for network designers and operators who want to understand the elements of data center design that apply across all hardware and software types.

I’m teaching a webinar on router internals through Pearson (Safari Books Online) on the 23rd of July. From the abstract—

A network device—such as a router, switch, or firewall—is often seen as a single “thing,” an abstract appliance that is purchased, deployed, managed, and removed from service as a single unit. While network devices do connect to other devices, receiving and forwarding packets and participating in a unified control plane, they are not seen as a “system” in themselves.
